Ok - it seems that seeing <Unknown>.<unknown> has cropped up intermittently before- we have a bug ref. PP-1710 for it, but there's no indication of cause on there. I'll follow up with the APP team to see if I can find out more...

Is there any possibility we'll be able to obtain a copy of your code (or if that's not possible, at least the executables) so we can investigate further? So far, this problem hasn't been reliably reproducible in-house.

I can't send you the code of this specific application because it belongs to my company, but I can reproduce the issue with any Windows Store app...

This project has the problem; I created it from the Grid App (XAML) template and didn't change anything in it.

Thanks- we'll take a look. Interesting you say any Store app does it, as we've tested various ones here without problem; so it may still prove to be environmental rather than application specific. I'll post back when I have an update.
